This paper shows the 3D slope stability analysis for municipal waste disposal Zoniówka II (quarters I and II) with numerical methods. The conditions of landslide were simulated for the quarter I. The theoretical situations were also analysed. It was assumed that retaining embankment was built from plastic or semi-solid consistency soil. The quarter 1 was also analysed assuming it's fully filled with wastes. The calculations results show, that main reason of landslide was improper soil material of retaining embankment. Further simulations proved that retaining embankment from plastic or semi-solid soil would approve waste disposal stability. The appropriate way of waste disposal is decreasing of moisture content of retaining embankment soil. Stability analysis for quarter II showed considerable different results between 2D and 3D calculations. These differences are the effect of higher precision of 3D modelling what gives a better opportunity to precisely reproduce the slope geology. This also gives a good chance to study the slope failure indicators. The 3D stability analyses of waste disposal allow investigation the progress of failure surface, its shape and range and also the volume of landslide. The accurate 3D geology model shows the influence of properties change on the calculations results. 3D calculations are however more laborious and require more powerful computers.
